Is Concrete Waterproof?

Concrete is one of the most popular building materials for professional construction workers and home-improvement hobbyists alike. It’s completely understandable why. Not only is concrete relatively affordable as a building block, but it can be adapted for so many different situations and is easy enough to use that the average person can figure it out with just a little bit of research. 

 

Of course, there is a reason some people make a full-time career out of contract work. Hobbyists can often find themselves in over their head if they underestimate a project. That’s why we’re going to address one of the most common questions we get from non-professionals who are working with concrete: Is concrete waterproof? 

 

The short answer: No, concrete is not waterproof, but it can be! Let’s take a closer look at why concrete is not inherently waterproof, and how to make it waterproof. 

 

One of the most confusing concepts to understand is that the waterproofness of concrete changes as concrete dries. Wet concrete is far more waterproof than concrete that has fully dried. That’s because concrete actually becomes more porous as it dries. 

 

The porousness of concrete can be confusing because concrete is not porous enough to act as a drain, but it will allow water to seep in. That means that even though you will see pools of water collecting on top of concrete, that water is still slowly seeping into the concrete itself. As that water gets into the concrete it will begin to wear away the surrounding material, this creates pockets inside the concrete that will continue to collect water in the future. 

 

Luckily, it’s really not that difficult to make your concrete project truly waterproof. There are two effective methods to choose from: a waterproof substance added to the mix of the concrete, or a substance that is applied to the surface of the concrete after it has dried. 

 

Mixing the waterproof substance into your concrete mixture initially is an easy and effective way to make sure your concrete stays waterproof. By mixing the waterproof substance into the mixture you take away the possibility that you applied it incorrectly, or missed a spot. 

 

While there are several products out there, the waterproof substance you put in the concrete mixture tends to be more expensive than the product that you apply after the concrete has properly dried. 

 

One of the major advantages of using a product that you apply after the concrete has dried, is that you can easily apply multiple layers or update the waterproofing over time. With a mix-based waterproofing your concrete could become less waterproof over time. 

 

Of course, the best way to make sure your concrete is properly waterproofed is to hire a professional. We encourage you to reach out to Razorback Concrete at www.razorbackconcrete.com
